3t+4(t-10)=t+20

3 t + 4 (t - 10) = t + 20

t = 10

Solution steps

3 t + 4 (t - 10) = t + 20

Expand

4 (t - 10) : 4 t - 40

3 t + 4 t - 40 = t + 20

Add similar elements:

3 t + 4 t = 7 t

7 t - 40 = t + 20

Move

40

to the right side

7 t = t + 60

Move

t

to the left side

6 t = 60

Divide both sides by

6

t = 10

6 x = 5 x + 10

x, 3 y - x = 2

E, I = \frac{E}{R}

x, 5 x - 7 y = 35

a, an = 3 n - 1
